In the event of a company wide outage where no one is able to connect to internal WIFI for LAD-LAN the issue may be the Cert located on MDCCAWEB shown here:
Current CERT is good till 3/15/2027 at 8:30 AM.
Certificate management duties (renew, export, delete, etc.) are handled via certlm.msc
This is located on 10.6.10.107 under IIS for the cert management.
In order for the cert to apply once you've issued the new one, you must delete the existing. We also restarted the server after completion and rebooted MDCWLC
After this it may take about 15 to 20 minutes for the computers to establish the connections or they may need a possible restart.
